The American Curl is a cat characterised by its unusual ears, which curl back from the face toward the center of the back of the skull. The breed originated in Lakewood, California, due to a spontaneous mutation. [1]
The first American Curls appeared as strays on the doorstep of the Rugas in Lakewood, California in June 1981. The black female, named Shulamith, gave birth to a litter of cats with the same curled ears, and so became the ancestor of all American Curls today. [2] [3] In 1986, an American Curl was exhibited at a cat show for the first time, and in 1992, the longhaired American Curl was given championship status by The International Cat Association (TICA). In 1999, the American Curl became the first breed admitted to the Cat Fanciers' Association (CFA) Championship Class with both longhair and shorthair divisions. [4]
The American Curl is a medium-sized cat 5–10 lb (2.3–4.5 kg), and does not reach maturity until 2–3 years of age. Females should be between 5–8 lb (2.3–3.6 kg) and males 7–10 lb (3.2–4.5 kg). [3]
American Curl kittens are born with straight ears, which begin to curl within forty-eight hours. After four months, their ears will not curl any longer, and should be hard and stiff to the touch at the base of the ear with flexible tips. A pet-quality American Curl may have almost straight ears, but showcats must have ears that curl in an arc between 90 and 180 degrees. A 90 degrees is preferable, but cats will be disqualified if their ears touch the back of their skulls.
Both longhaired and shorthaired American Curls have soft, silky coats which lie flat against their bodies. They require little grooming and enjoy spending time with their owners and generally get along well with other animals and people who aren't their owners.
The American Curl, while still an uncommon breed, is found across the world in the United States, Spain, France, Japan, Russia, and many other countries.
Various matings between cats with curled ears and cats without curled ears revealed a dominant inheritance of the curl gene. Sex-linked distribution was not found. The mutant gene was designated as curl and is symbolized by Cu. [1] Another mutation of the ear pinna was found in Scottish Fold cats. In these cats both heterozygous and homozygous (FdFd) cats, animals suffer from osteochondrodysplasia. [5] The question arises if homozygous curls (CuCu) could also be affected by cartilage formation defects and bone abnormalities. However, observations of a CuCu cat over two years showed no sign of anomaly. [1]
The Siamese cat is one of the first distinctly recognised breeds of Asian cat. It derives from the Wichianmat landrace. The Siamese cat is one of several varieties of cats native to Thailand. The original Siamese became one of the most popular breeds in Europe and North America in the 19th century. Siamese cats have a distinctive colourpoint coat, resulting from a temperature-sensitive type of albinism.
The Selkirk Rex is a breed of cat with highly curled hair.
The Maine Coon is a large domesticated cat breed. One of the oldest natural breeds in North America, the breed originated in the U.S. state of Maine, where it is the official state cat.
The Cymric is a Canadian cat breed. Some cat registries consider the Cymric a semi-long-haired variety of the Manx breed, rather than a separate breed. Except for the length of fur, in all other respects, the two varieties are the same, and kittens of either sort may appear in the same litter. The name comes from Cymru, the indigenous Welsh name of Wales, even though the breed is not associated with Wales. The name may have been chosen to provide a "Celtic" sounding moniker for the breed. While the breed's Manx bloodline originated from the Isle of Man, the long-haired variant is claimed to have been developed by Canada. The breed is called the Longhair Manx or a similar name by some registries.
The Scottish Fold is a distinctive breed of domestic cat characterised by a natural dominant gene mutation associated with osteochondrodysplasia. This genetic anomaly affects cartilage throughout the body, causing the ears to "fold", bending forward and down towards the front of the head. While this trait contributes to the breed's unique appearance, often described as "owl-like", it also causes health problems.
The Munchkin is a breed of cat characterized by its very short legs, which are caused by genetic mutation. Compared to many other cat breeds, it is a relatively new breed, documented since 1940s and officially recognized in 1991. The Munchkin is considered to be the original breed of dwarf cat.
The American Bobtail is an uncommon breed of domestic cat which was developed in the late 1960s. It is most notable for its stubby "bobbed" tail about one-third to one-half the length of a normal cat's tail. This is the result of a cat body type genetic mutation affecting the tail development, similar to that of a Manx cat. The breed is not related to other short-tailed breeds, such as the Cymric cat, or the Japanese Bobtail or Kurilian Bobtail, despite the similar name and physical type—the breeding programs are entirely unrelated, and the genetic mutation causing the bobbed tail are known to be different, as the mutation causing the American Bobtail's short tail is dominant; comparatively, the Japanese Bobtail, for example, has a tail mutation that is recessive.
The Burmese cat is a breed of domestic cat, originating in Burma, believed to have its roots near the Thai-Burma border and developed in the United States and Britain.
The Ragdoll is a breed of cat with a distinct colorpoint coat and blue eyes. Its morphology is large and weighty, and it has a semi-long and silky soft coat. American breeder Ann Baker developed Ragdolls in the 1960s. They are best known for their docile, placid temperament and affectionate nature. The name Ragdoll is derived from the tendency of individuals from the original breeding stock to go limp and relaxed when picked up. The breed is particularly popular in both the United Kingdom and the United States.
The Bombay cat is a short-haired breed of domestic cat. Bombays are glossy solid black cats with a muscular build, and have characteristic large bright copper-golden eyes. The breed is named after the Indian city of Bombay (Mumbai), referring to the habitat of the Indian black leopard.
A dwarf cat is a domestic cat with dwarfism due to rare genetic mutations that cause a disproportionate feline body. The mutation usually leads to significant health problems. Unlike undersized cats of normal proportions, dwarf cats suffer from the genetic mutations osteochondrodysplasia and achondroplasia. These genetic disorders of bone and cartilage are typically manifested as abnormal bone shape, poor growth or lack of growth, bowing of the limbs to the side – front legs are more likely to be affected, and spinal malformations.
The Ukrainian Levkoy is a cat breed with inward-folding ears and little to no hair. The cats are of medium size with a longish body, appearing both muscular and slender. They have soft, elastic skin; an excess of which leads to a wrinkled appearance. The breed is not recognized by any major, international cat fancier and breeder organizations, only Ukrainian and Russian clubs.
The Abyssinian is a breed of cat with a distinctive "ticked" tabby coat, in which individual hairs are banded with different colours. They are also known simply as Abys.
The Minuet is a hybrid mix of Persian and Munchkin cat breeds. Categorized by The International Cat Association (TICA) as a domestic hybrid, "developed from a deliberate cross between two existing domestic breeds, incorporating characteristics of both parental breeds into the new mix." The Minuet cat is characterized by its short legs, as a result of the dwarfism-mutation derived from the Munchkin breed.
The Persian cat, also known as the Persian Longhair, is a long-haired breed of cat characterised by a round face and short muzzle. The first documented ancestors of Persian cats might have been imported into Italy from Khorasan as early as around 1620, however, this has not been proven. Instead, there is stronger evidence for a longhaired cat breed being exported from Iran from the 19th century onwards. Persian cats have been widely recognised by the North-West European cat fancy since the 19th century, and after World War II by breeders from North America, Australia and New Zealand. Some cat fancier organisations' breed standards subsume the Himalayan and Exotic Shorthair as variants of this breed, while others generally treat them as separate breeds.
Cyprus cats, also known as Cypriot cats, Saint Helen cats, and Saint Nicholas cats, are a landrace of domestic cat found across the island of Cyprus. A standardized breed is being developed from them; among cat fancier and breeder organizations, it is presently fully recognized by the World Cat Federation (WCF), with breeding regulated by the World Cat Congress (WCC), under the name Aphrodite's Giant; and provisionally by The International Cat Association (TICA) as the Aphrodite. All three organizations permit shorthaired and semi-longhaired versions and no out-crossing to other breeds.
The Highlander is a new breed of cat. The unique appearance of the Highlander comes from the deliberate cross between the Desert Lynx and the Jungle Curl breeds, also recently developed.
